DOOR INSERTION WITH NAME PLATE Filed May 8, 1950 Patented May 30, 1933 UNITED STATES PA.UL HOIEEB, OF MUNICH, GERMANY DOOR INSE-BTION W ITH NAME PLATE Application filed. May 8, 1930, Serial No.

This invention relates to a door insertion with name plate and with an arrangement designed to uncover a narrow slot inthe insertion for peeping through a cut out portion of the door or to uncover the entire cut out portion of the door for speaking and for passing articles through. For this purpose a metal frame is employed framing the cut out portion of the door, on the inner side of which frame a box is hinged adapted to be laid down into the horizontal position against the action of a spring. This box covers the opening in the frame and carries the name plate behind a cut out portion in its front wall. This box is further partly cutout Within the frame opening in its front wall and rear wall, and these cut out portions are covered by a slidesupported on springs movable in opposition to these springs and adapted to uncover the cut out parts in the box above the name plate for peeping through the door, without it bemg necessary to flap down the box.

Two embodiments of the invention are illustrated by way of example in the accompanying drawing in which:

Fig. 1 is a rear view of the arrangement.

Fig. 2 is a vertical section through the centre of the arrangement.

Fig. 3 shows another form of construction in rear elevation.

Fig. 4 is a vertical section through the centre of Fig. 3.

Fig. 5 is a horizontal section through the centre of Fig. 3.

The arrangement shown in Figs. 1 and 2 consists of a frame-shaped insertion 1, 2, fitting in a corresponding cut out portion of a door the flat part 1 of said insert sur- 0 rounding the cut out portion of the door,

whereas the conical part 2 penetrates into this cut out portion. On the inner side of the door the cut out portion of the door is framed by a metal frame 3, fastened to the door, which has an opening corresponding to that of the insertion frame 1, 2 and carries at its lower end by means of hinges 4 a metal box 6, 10, which covers the opening of the insertion frame 1, 2 and can be laid 0'. down into horizontal position. The box is 450,?52, and in Germany May 13, 1929.

acted upon by springs 5, which tend to swivel the box into the closing position. If the box is swung into the horizontal position, the entire opening of the frame is freed, and it is possible to talk or hand articles through the door. The front wall 6 of the box is cut out according to the frame opening 12, and a name plate 8 is inserted in the box in this opening together with a glass cover plate 9. The name plate is slightly lower than 69 the frame opening so that above the name plate a narrow strip of the frame opening remains free for peeping through. The rear wall 10 of the box is cut out for the largest part, but the cut out portion 11 is 55 covered by a slide 12 inserted in the box. This slide rests in the box on springs 13 and has a handle 14, projecting from the'rear wall of the box, by means of which handle the slide can be depressed towards the bot- 7.0 tom of the box so that it leaves free a narrow stri of the opening 11 of the rear wall of the ox. It is then possible to peep through this open strip and through the glass plate above the name plate through the opening of the frame, in order to observe the person standing on the outer side of the door. In the upper part of thebox a slidable latch 15 is inserted, controlled by a spring 16 and adapted to be operatedby means of a knob 17 projecting from the box. The latch engages in a slot with a slot. 15 in a hook 18, fastened on the frame plate 3 and thereby secures the box in closing position. The box has a slot 6' at a suitable. point, through which the hook 18 can penetrate into the box and into the latch 15. On shifting the latch towards the right, the latch will be released from the locking hook so that the-box can be turned down in oppo- 9 sition to the action of its spring. On releasing the box, it jumps back into its closing position through the action of its springs 5. A strut 19 is situated in the box and engages over the upper edge of. the name plate, thereby preventing the same from being displaced with the slide12. In the lower part of the frame 1 a cut out portion 20 is provided for inserting letters and behind this cut out portion a spring flap 21 we is hinged on the frame part 2 by means of hinges 22.

In the form of construction shown in Figs. 3 to 5 the frame consists only of a flat plate with an aperture 24 and a letter box slot 25. The box and closing flap 28 are hinged on hinges 26 and 27 respectively. The box is situated in thedoor aperture and its front wall 29 is recessed and in this recess the name plate 30 and glass plate 31 are inserted. Over the two side edges of the front wall a cover plate 32 isapplied, which is bent over a U-shape on its side edges and forms slide grooves 40. The glass plate 31 and the name plate 30 are held by this cover plate 32 in the depression inthe front wall of the box. The cover plate 32 is cut out, according to the frame plate 23. The name plate leaves a small strip of the glass plate and of the aperture of the cover plate 32 and of the frame plate 23 free for peeping through, and in the front wall and in the rear wall of the box a slot 33 and 34 respectively are provided above the name plate, so that it is possible to peep through the slots 34 and 33, the upper part of the glass plate and the upper part of the aperture of the cover plate 32 and of the frame plate 23. The View is however impeded by the slide 35, which rests on springs 36 in the box and can-be moved downwards by the handle 37. If the slide is depressed, the view through the slots 3 and33becomes free. In'the upper part of the box a slidable spring latch 38 is arranged, which engages in a hook 39 on the frame 23 and holds the box in closed position.

, I claim:

1. On a door insertion having a letter slot with hinged flap and name plate in said flap, the combination of a closed metal box, hingedly fixed on the insertion in horizontal positionadapted to form in this position a table behind the letter slot in the door, a front wall of said box cut out in a shape corresponding to that of the letter slot, a rear wall of said box having an aperture, a spring controlled slide adapted to be shifted against the action of its spring in said box and to expose a narrow portion of the apertures in said rear wall and in said front wall abovesaid name plate to give a clear view and a slidable latch in the upper portion of said box adapted to hold said box in closed position on the insertion.

2. On a door insertion having a letter slot wlth'hmged flap and name plate on said fiap, the combination of a metal frame surrounding the letter slot, a conical portion on said frame penetrating into the letter slot, a closed metal box hinged to said coni cal portion and foldable into horizontal position adapted to form in this position a table behind the letter slot, a front wall of said the insertion.

3. On a door insertion having a letter slot with hinged flap and name plate, the combination of a closed metal box adapted to swing into horizontal position. and to form in this position a table behind the letter slot, a front wall of said box having a slot and a recessed portion adapted to accommodate said name plate, a cover plate cut out to correspond with the letter slot and having grooves on its side edges for slipping onto the side edges of the front wall of said box, a rear wall of saidbox having a slot registering with the slot in said front plate, a spring controlled slide in said box adapted to close said slots and to move against the action of its springs and thereby expose said slots giving a free view through the insertion, and means for holding said box in closed position. 1

In testimony whereof I a'fiix my signature.
